composer require-dev的作用
"require-dev": {
"phpunit/phpunit": "~4.0",
"phpspec/phpspec": "~2.1",
"barryvdh/laravel-ide-helper": "~2.0"
}
以上的require-dev大致意思是在开发环境下加载以上依赖包，
问题来了，composer 是怎么判断当前环境是正式环境还是开发环境呢？
还是说在正式环境需要把require-dev节点手动删除吗？

Lists packages required for developing this package, or running tests, etc. The dev requirements of the root package are installed by default. Both install or update support the --no-dev option that prevents dev dependencies from being installed.
楼主理解没错，require-dev 下的包都会被下载的，不管是dev还是prod环境。这和 npm 的 devDependencies 一样的道理。
现在大家的存储空间很大，多装几个包占不了多少。方便开发才是这个包管理工具考虑的重点。
